Application filed July 29, 1512. Serial No. 712,174.

To all whom z may concern:

Be it known that l, "WILLIAM S. MORRIS, a citizen of the United States, and resident of St. Louis, Missouri, have invented certain new and useful Improvements in Reinforced- Cement Poles, of which the following is a specification containing a full, clear, and exact description', reference being had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in reinforced cement poles, and t-he object of my invention is to construct a monolithic cementitious pole, cruciform in cross section and tapering from end to end, in which there is an improved reinforce which fully reinforces and trusses the structure, both as to length and cross section.

WVith the above purposes in view my invention consists in certain novel features of construction and arrangement of parts as will be hereinafter more fully described, pointed out in the claims and illustrated by the accompanying drawings, in which- Figure 1 is an elevation of a complete pole constructed according to my invention; Fig.

2 is an enlarged transverse sectional elevation of the pole showing the arrangement of my improved reinforce; Fig. 3 is a perspective view illustrating a portion of my improved reinforce; Fig. 4 is an elevation of a fragment of the pole in a horizontal position and illustrates the arrangement of the reinforce; Fig. 5 is an elevation of a fra-gment of the pole taken in the direction of the arrow 5 in Fig. 2; and Fig. 6 illustrates fragments of the pole, partly in section, taken in the direction of the arrow 6 in Fig. 2, and illustrates a kink or bend in one of the reinforcing rods to clear an opening through the pole. v

Referring by numerals to the accompanying drawings: 7 designates the body portion of the pole and 8 wings forming a part of the pole, the body portion and wings forming in cross section a cruciform which tapers from end to end. At intervals throughout the length of the pole and extended through the body portion 7 there are openings 9 arranged to receive a climbing device (not shown). Extended through the body portion, adjacent the top of the pole, there are openings 10 at right angles to the openings 9, and arranged to receive cross arms, (not shown) Extended throughout the length of the pole and embedded therein is a metallic reinforce comprising rods 11 which are located adjacent the free ends of the wings 8, and rods 12 located in the body portion 7. A pair of the rods 11 and one of the rods 12 have connected therewith a reinforcing element 13, constructed of hardware cloth, or other sheet material such as metallic lathing and in cross section is substantially L-shape. The remaining rods 11 and the other rod 12 are secured to a reinforcing element 13. These two elements are secured at their central portions to each other by means of a bond 15, which bond also connects with the rods 12. The free ends of each of the reinforcing elements 13 and let are secured at intervals to the rods -11 by means of bonds 16.

At intervals throughout the length of the pole there are the crossed stay-rods 17, the ends of which are secured to the rods 11 by means of the bonds 18, and at the centra-l portions are secured by the bonds 15.

` By reason of the rods 11 and 12 being connected throughout their lengths by the reinforcing element constructed of hardware cloth, it is obvious that the body portion 7 and the wings 8 are trussed in all directions, and it is obvious further that it is essential to hold the rods 11 and 12 parallel, hence l have provided the rigid stay-rods 17 at intervals throughout the length of the pole.

-Where the rods 12 intersect one of the openings 9 or 10 I form a kink 19, as shown in Fig. 6.

I claim:

1. A reinforce for cement poles which are cruciform in cross section, comprising a pair of rods which are arranged to be embedded in the body of the pole, and rods which are arranged to be embedded in the wings of the pole, crossed stay-rods connecting the first mentioned rods for holding said rods parallel, and a pair of reinforcing elements formed of hardware cloth, each having their margins secured to a pair of the rods arranged to be embedded in the wings of the pole and their central portions secured to the rods arranged to be embedded in the body of the pole.

2. A reinforce for cement pole cruciform in cross section, comprising a pair of sections of hardware cloth arranged to be eX- element 14 which is the counterpart of the ico tended the length of a pole and L-shape in cross section, a pair of rods extended the length of the sections of hardware Cloth and arranged to be engaged by the central portions of said sections of cloth, a rod at the free margin of each of said sections of cloth7 means for securing said sections of cloth to said rods, and rigid reinforcing elements for holding said rods in parallelism.

ln testimony whereof, I have signed my name to this specification, 1n presence of two 3,0 subscribing witnesses.
